Android App Build Fails After Installing flutter_secure_storage

Closed this issue 9 months ago · 1 comments

Hello,

I'm having an issue with the flutter_secure_storage package. After installing it, I'm unable to build my Android app. The build process fails with a message indicating that my app has exceeded the 64K method limit and requires Multidex support.

Here's the error message I'm seeing:

Launching lib/main.dart on sdk gphone64 arm64 in debug mode...
Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

[!] App requires Multidex support
    Multidex support is required for your android app to build since the number of methods has exceeded 64k. See https://docs.flutter.dev/deployment/android#enabling-multidex-support for more information. You may pass the --no-multidex flag to skip Flutter's multidex support to use a manual solution.

    Flutter tool can add multidex support. The following file will be added by flutter:

        android/app/src/main/java/io/flutter/app/FlutterMultiDexApplication.java

cannot prompt without a terminal ui
Error: Gradle task assembleDebug failed with exit code 1


Exited (1).

I understand that maybe enabling Multidex support can solve this issue, but I'm concerned about the potential impact on my app's performance and size. I'd like to avoid enabling Multidex if possible. More info:

Is there a way to use flutter_secure_storage without exceeding the 64K method limit, or is there a workaround for this issue?

Thank you for your help.

Hello again,

I wanted to provide an update on this issue. I was able to resolve the problem by increasing the minSdkVersion in my build.gradle file to 21. Here's the updated line in my build.gradle:

minSdkVersion 21

I'm closing this issue now. Thank you for your attention to this matter.
